Contaminated Land Investigation

Design


Detailed intrusive investigations are often required in order to establish ground properties and contamination characteristics (soil, groundwater and land gas) of the site.

When dealing with land affected by contamination investigations are carried out based on the technical framework for applying a risk management process as detailed in CLR 11 (Model Procedures for the Management of Land Contamination). A preliminary conceptual model and risk assessment is prepared as part of the contaminative uses desk study and allows for design of the site investigation.

Investigation


By combining our wide range of experience (over 16,000 projects in the past 40 years), with our knowledge of the latest investigation and construction techniques, we are able to provide innovative and cost effective investigation solutions.

Having our own site staff and specialist site equipment allows us to tailor each investigation to our client's needs. Our site staff all hold CSCS cards, are trained in logging to BS5930 and have a wealth of practical site experience.
